DP-300 Implement a secure environment Practice Question
You need to ensure that an Azure SQL Database uses Microsoft Entra-only authentication. You have configured the server to disallow SQL authentication. What additional step is required to prevent users from creating SQL logins?
⚠ Common exam trap
Many exam-takers assume disallowing SQL authentication implicitly prevents SQL login creation, but in Azure SQL Database, authentication and authorization are separate concerns—the setting only controls authentication, not the ability to create logins.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Revoke the 'CREATE LOGIN' permission from all users except the Entra admin.
Disallowing SQL authentication at the server level prevents users from authenticating with SQL logins, but it does not revoke the ability to create new SQL logins. Users with the 'loginmanager' fixed server role or the 'CREATE LOGIN' permission can still create SQL logins, which would exist in the master database even though they cannot be used for authentication. To fully enforce Microsoft Entra-only authentication, you must explicitly revoke the 'CREATE LOGIN' permission from all users except the Entra admin, ensuring no new SQL logins can be created.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Revoke the 'CREATE LOGIN' permission from all users except the Entra admin.
Why this is correct
This prevents users from creating new SQL logins.
- ✗
Remove the 'loginmanager' fixed server role from all users.
Why it's wrong here
Removing the role revokes the ability, but revoking the permission directly is more granular.
- ✗
Enable auditing to detect login creation attempts and alert the security team.
Why it's wrong here
Auditing does not prevent creation.
- ✗
No further action needed; disallowing SQL authentication prevents any SQL login creation.
Why it's wrong here
Disallowing SQL authentication prevents authentication, but users with permissions can still create logins.
